Pinhole Device closures for hole in heart

Different types of closure devices are used to close a hole or an opening between the right and left sides of the heart. Some of these birth defects are located in the wall (septum) between the upper chambers (atria) of the heart.

The percutaneous closure of patent foramen ovale (PFO) and ASD is performed using a special closure device. The device is folded or attached on to a special catheter, similar to the catheter used during your catheterization. The special catheter is inserted into a vein in the leg and advanced into the heart and through the hole. The device is slowly pushed out of the special catheter allowing each side of the device to open up and cover each side of the hole (like a sandwich), closing the hole or defect. When the device is in proper position, it is released from the special catheter. Over time, heart tissue grows over the implant, becoming part of the heart. The PFO and ASD closure procedure is monitored by X-ray and ultrasound.

Procedure:

In most instances, this is performed under local anaesthesia. First you will undergo an echocardiogram to determine the size and location of the hole in your heart. An echocardiogram will be performed to confirm the position of the hole and assess the progress of the procedure throughout.

There are few devices available to use such as Amplatzer, Occlutech and Lifetech devices. All these device consists of two wire mesh discs filled with polyester fabric (see photo above). When the device is in proper position, the device is slowly pushed out the catheter until the discs of the device sit on each side of the hole (like a sandwich).

Once the cardiologist is satisfied with placement of the device, it is released from the special catheter and is now implanted in your heart. Over time, heart tissue grows over the implant, becoming part of the heart.
